LINE CLAMP.

Application filed November 8, 1921. Serial No. 513,640.

[o @ZZ LU/0m it may concern.'

Be it known that I, Josnri-I it. IIUNZ, a citizen of the United States,and a resident of Hartford, in the county of Hartford and State ofConnecticut, have invented new and Improved Iiine Clamps, of which thefollowing is a specification.

My invention relates to that class of devices that are employed forsecuring an end oi a length oi" line or rope, and an objectof myinvention, among others, is to provide a device of this class that shallbe simple in construction, durable, and particularly eliicient inoperation.

One form of line clamp embodying my invention and in the constructionand use of which the objects herein set out, as well as others, may beattained, is illustrated in the accompanying drawings, in which- Figurel is a side view of my improved line clamp showing one end of a lineattached thereto and the opposite end held by the clamp.

Figure 2 is a view in section through the clamp illustrating its methodof operation. Figure 3 is an end view of the clamp.

Figure 4 is a view illustrating a modified form of the structure.

My improved clamp is not confined in its use for the purpose of securingthe end of a line employed Jfor any special purpose, it beingparticularly applicable for securing the end of a line or lines that isor are required to be loosened at certain times, and as such a situationoccurs in the use of pulley clothes lines, I have selected such for thepurpose ot illustrating my invention herein, similar conditions alsoexisting in guy-ropes for tents &c. s

In the accompanying drawings the numeral indicates the attached end, asof a pulley line, and 6 the free end thereof, the at` tached end 5 beingsecured as by a knot to my improved fastening that comprises a body 7having a loop S on one side within which the attached end 5 of the lineis secured, and a groove 9 on the side opposite the loop 8. A clamplever l0 is pivotally mounted between the sides 11 of the clamp, saidsides with the base 7 forming the groove 9. The lever comprises aclamping arm l2 and an actuating arm 13, the latter preferably beinglonger from the pivot 11i than is the clamping arm l2. l The lever isformed and mounted between the sides l1 so that the end of the actuatingarm 13 will be substantially in line with the attached and free ends 5they are drawn taut, and especially as shown in Figure 2 of thedrawings. In this position it will be noted that the strain on the linecauses the tree end 6 to exert a pull on the actuating arm 13 of thelever, thereby forcing the clamping arm l2 into close engagement withthe free end of the line, thus clampingv it tightly between the end ofthe clamping arm l2 and the bottom of the groove 9, and the more thestrain exerted upon the free end 6 oi the line the tighter will be theengagement of the clamping arm l2 with the line. The edges of the lever10 in contact with the line may be 'corrugated it' desired, lin order toincrease the frictional resistance of the lever to movement of the line.

It will be seen that the device is of particular advantage when used inconnection with a pulley line or with the guy rope of a tent or thelike, as all that is required to tighten the line is to pull downwardlyon its tree end thus pulling it through the groove 9, this act looseningthe lever so that no obstruction to this movement of the line will beoccasioned. However, just as soon as the pulling strain on the end ofthe line is relieved it will be taken up by that portion of the line incontact with the actuating arm 13 thereby forcing the lever into tightengagement with the line and preventing its end from escaping from thehold of the clamp.

In accordance with the provisions of the patent statutes, I havedescribed the princi-- ples of operation of my invention, together withthe device which I now consider to represent the best embodimentthereof; .but I desire to have it understood that the device shown isonly illustrative, and that the invention may be carried out by othermeans.

In the form of the device as shown in Figure Ll a double structure isformed, the loop 8 being dispensed with and the end oi' the line that,in that form of the device, is secured to the loop, is passed throughthe body 7 and is held by a lever and clamp similar to that hereinbeforedescribed.

I claiml. A line clamp including a body having a groove therein, a leverpivotally attached to the body within said groove and comprising anactuating arm, and a clamping arm, and means located on said bodyopposite said and 6 of the line when actuating :mn and at the same endof the hody :for attachment of the end of it line thereto.

2. A line clamp including a rectanguiariy 5 shaped body having agroovetherein, e
